Key result
Combined walking and cycling improves 6-minute walk distance by ~169 m in post-AVR heart failure.
Why the study?
Patients with CHF after AVR often experience a decline in aerobic capacity despite improved heart pump function, and this case report evaluated whether combined walking and static bicycle exercise improves functional capacity.
Does a phase II cardiac rehabilitation program combining walking exercise and static bicycle exercise improve aerobic capacity (6MWT) in a patient with NYHA Class II congestive heart failure after aortic valve replacement?

A structured 12-session phase II cardiac rehabilitation program combining walking and static cycling safely improved 6-minute walk distance, METs, and ejection fraction in a patient with NYHA Class II heart failure following aortic valve replacement.
Patients with congestive heart failure (CHF) after aortic valve replacement (AVR) often experience a decline in aerobic capacity even though heart pump function shows improvement. Structured aerobic exercise is thought to optimize cardiovascular adaptation and accelerate functional recovery after surgery. This case report aims to evaluate the effectiveness of a combination of walking exercise and static bicycle exercise in improving functional capacity in patients with Functional Class II CHF after AVR, as assessed using the Six Minute Walking Test. A 56-year-old man underwent 12 sessions of phase II cardiac rehabilitation over four weeks. All exercise sessions were stable with no signs of intolerance. This intervention proved to be safe and effective in improving aerobic capacity, cardiovascular efficiency, and overall physical function. A simple, structured, and easy-to-implement exercise program can provide significant clinical benefits to CHF patients after AVR.

Ammar et al. (2026) conducted a case report in Congestive Heart Failure (CHF) Functional Class II post Aortic Valve Replacement (AVR) due to rheumatic heart disease (n=1). Phase II cardiac rehabilitation combining walking exercise (track and treadmill) and static bicycle exercise vs. Baseline pre-rehabilitation assessment (Week 3) was evaluated on Six-Minute Walk Test (6MWT) distance (meters). Combined walking and static bicycle exercise over 12 sessions improved 6-minute walk distance from 311 m to 480 m, METs from 3.8 to 4.9, and EF from 55% to 59% in a post-AVR CHF patient.
